VALVE-GOVERNING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 733,757, dated July 14, 1903.

Application filed August 7, 1901, Serial No. 71.194. (No model.)

To all whom it may concern.-

Be it known that I, WALTER W. SPINNEY, a subject'of the King of Great Britain, residing in the borough of Manhattan, city,county, and State of New York, have invented certain new and useful Improvements in Valve- Governing Mechanism, of which the following is a specification.

My invention relates to mechanism for governing the position of valves according to the pressure of a liquid or gaseous fluid.

The object of the invention is to provide a simple, readily-adjusted, and efficient mechanism of the above-indicated class.

The novel features of my invention will appear from the description following hereinafter, and particularly from the appended claims.

Reference is to be had to the accompanying drawings, in which- Figure l is a sectional elevation of my improved valve-governing mechanism. is a section-valve on line2 2 of Fig. 1, and Fig. 3 is a plan with partsbroken away.

A is the casing in which the valve B is mounted to turn, said casing being provided with an inlet A and an outlet A The valve is suitably journaled at one end in said casing A and at the other end in a stuffing-box C, secured to the casing by screws D. The stuffing-box contains a packing E, which is held in position by means of a screw-cap F. The valve stem or spindle B is extended through the said cap F and carries exteriorly thereof a crank-arm B having a loose pivotal connection with arod G, extending upwardly and having a guided vertical movement in a bushing H, set in an opening at the bottom of a casing or box H, which is connected with the valve-casing Afor instance, by means of screws D. The upper Fig. 2.

of said box to allow of an easy movement of the cup. The lower surface of the cup K is beveled and is engaged by slides L, movable radially at the bottom of the box H, said slides being likewise beveled. Each slide may be adjusted inward or outward by means of a screw M,-provided at its inner end with a head M, fitting a corresponding groove in the slide L. Check-nuts N serve to hold the screws M in position after adjustment. It will be understood that by means of these screws and slides the cup K may be shifted up or down, thereby adjusting the tension of the spring J. The upper end of the extension 11 is closed by a cap 0 and communicates laterally with a pipe P in permanent communication with the pipe P,Whl6h is a branch from a pump-delivery pipe leading to the place where the Water or other fluid is used. It will therefore be obvious that the pressure within the upper portion of the extension H will always be equal to the pres: sure of the fluid at the place of consumption.

The motive fluid, as steam, for the engine which drives the pump passes through the casing A when the valve Bis open and travels therefrom through a pipe P to the engine. From the delivery side of the pump a suitable delivery-pipe leads to the place of con sumption, and from this delivery-pipe the pipes P P lead above the piston I. It will thus be understood that the position of the piston I will depend on the back pressure existing in the pipes P and P. It will of course be understood that the tendency of the a practically constant pressure at the point I,

of delivery or consumption.

I desire it to be understood that instead of the piston I may use a diaphragm, and the claims are to be interpreted as covering this equivalent.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination of the piston-chamber, the piston mounted to move therein and provided with rods projecting therefrom at opposite sides, one of said rods extending through one end of the chamber, a stationary guide located between the other end of the chamber and the piston and engaging the other piston-rod, a valve-casing and valve therein, and aconnection between said valve and that piston-rod which projects through the end of the chamber.

2. The combination of the valve-casing, the valve mounted to turn therein, the piston chamber or casing, the piston in said chainchamber, the spring bearing against the pis- J ton and against said plate, transversely-movable adjusting slides provided with inclined surfaces engaging the plate, and an operating connection from the piston to the valve.
